Tilting board capable of adjusting angle of tilt

ABSTRACT

A tilting board for a human being operated includes an operation plate, a base plate rotationally connected to the operation plate, a sliding rail fixed on the base plate, and an adjustment member. The sliding rail is fixed on the base plate and defines a plurality of pairs of opposite slots. One end of the adjustment member abuts against the operation plate and the other end of the adjustment member is positioned between one of the pairs of opposite slots. The degree of incline of the tilting board can be changed by moving the adjustment member from the pair of opposite slots to another one of the pairs of opposite slots.

DETAILED DESCRIPTION

Referring to FIGS. 1-3, a tilting board 100 includes an operation plate 10, a base plate 20, a sliding rail 30, and an adjustment member 50.

The operation plate 10 includes a stop bar 12 along the base plate 20. The operation plate 10 is rotationally connected to the base plate 20. In the embodiment, the operation plate 10 is connected the base plate 20 via two hinges 25 fixed to ends of the operation plate 10 and the base plate 20.

The sliding rail 30 includes a rail 32 and two clamping pieces 34. The rail 32 and two clamping pieces 34 are all fixed on the base plate 20. The two clamping pieces 34 are parallel to each other with the rail 32 between them. Each clamping piece 34 defines a number of slots 38. The number of slots 38 face the rail 32 and are perpendicular to the base plate 20.

Also referring to FIG. 4, the adjustment member 50 is positioned between the two clamping pieces 34. One end of the adjustment member 50 is slidably positioned on the rail 32. In the embodiment, one end of the adjustment member 50 defines a sliding groove 52. The adjustment member 50 is sleeved on the rail 32 via the sliding groove 52 such that the adjustment member 50 can slide along the rail 32. Two restriction pins 40 protrude from the base plate 20 and are adjacent to two ends of rail 32. The adjustment member 50 is restricted to sliding between the two restriction pins 40. Two sides of the rail 32 respectively define a ditch 35 along the lengthwise direction of the rail 32 from one end to the opposite end. The adjustment member 50 includes two guiding portions 54 respectively protruding from two sides of the groove 52. The two guiding portions 54 are respectively received in the two ditches 35, such that the adjustment member 50 has only one degree of motion along the rail 32. The other end of the adjustment member 50 abuts against the operation plate 10 to support the operation plate 10, forming an angle between the operation plate 10 and the base plate 20. A magnet 55 is fixed on the said other end of the adjustment member 50. A metal sheet 14 is fixed on a surface of the operation plate 10 adjacent to the adjustment member 50. The metal sheet 14 is positioned where the surface touches the magnet 55, thus the operation plate 10 and the adjustment member 50 have a magnetic attraction for each other.

The adjustment member 50 defines a through hole 56 perpendicular to the clamping piece 34. An elastic member 60 is received in the through hole 56. Two clips 70 are respectively positioned at two ends of the elastic member 60 and partly received in the through hole 56. The end of the clip 70 exposed at the through hole 56 is received in one of the slots 38. The two clips 70 overcome the elastic force of the elastic member 60 in moving from one slot 38 to another slot 38 when the adjustment member 50 slides along the rail 32, and such moving changes the angle between the operation plate 10 and base plate 20.

In the embodiment, a handle 80 protrudes from the adjustment member 50. An operator pushing on the handle 80 makes the adjustment member 50 slide along the rail 32.
